Abstract：
Taking the Liuyanghe tunnel for an example, the 10 questions happened in the process of field monitoring were studied, and the corresponding countermeasures were discussed. The results showed: the effect of river level variation on stability of vertical displacement datum point should be noticed; the defects of the formula transforming monitoring strain of the secondary lining to its axial force and bending moment should be noticed; as time went by, the contact pressure between initial lining and surrounding rock might increase or decrease; the made device installing the pressure cell could be referred by the similar projects; the suggested safeguard procedures of the monitoring instruments, remedial measures of the missing datas and treatment measure of the abnormal datas could be referred by the monitoring of the similar underwater tunnel.
